Great, but lacks an archive function Rated 4 out of 5 stars

Lightning is a valuable add-on to the Thunderbird application. I am using it for more than a year. There is however no easy way to archive old events. The add-on "Purge Events Plus" by "Mark" does what it says: It purges old events rather than archive them. Am I the only user who values history?

This review is for a previous version of the add-on (2.6).
